History of REO Trucks

  2006 marks the 100th anniversary of the momentous day when the American company REO, founded in 1904 by Ransom and Olds, began manufacturing trucks. Soon this field of activity became decisive for her, REO trucks became widespread in North America. In the late 1930s, the family of proposed models with hood and half-hood layout included dozens of options, which included pickups, light vans, flatbed trucks, special vehicles for urban services.


In an effort to increase the useful length of the body without increasing the overall length of the vehicle, the designers proposed a new truck layout with a cab heavily pushed over the engine, mounted strictly above the front axle. To facilitate entry into the high cabin, a pair of steps were installed on the wings, and access to the engine for maintenance was carried out using a removable hood. Two families of trucks of a similar layout had the designations 1 B7M and 2 B7M. They were designed to carry 4.8 and 6.0 tons of cargo and were equipped with a 6-cylinder low-speed gasoline engine with a capacity of 73 and 83 hp. respectively. The gearbox was 4-speed, there was a vacuum booster in the hydraulic brake system. Among the interesting technical features of these machines, we note the possibility of installing a two-speed rear axle, the use of a seven-bearing crankshaft, aluminum pistons, and a multi-link metal chain in the camshaft drive.
